  25 ### Conventions for build systems.
  26 ###
  27 ### This script is designed to work with a variety of `make'-based build
  28 ### systems, but there are a number of conventions which must be followed if
  29 ### this is going to work properly.
  30 ###
  31 ###   * There must be a `configure.ac', `configure.in', or `.links' file, or
  32 ###     a `.git' directory in the project top-level, so that we can find it.
  33 ###
  34 ###   * The following `make' variables must be assigned in the top-level
  35 ###     Makefile, after `mdw-build' has constructed it.
  36 ###
  37 ###     distdir         The name of the top-level project directory in the
  38 ###                     source distribution, and the base name for
  39 ###                     distribution archives; should be of the form
  40 ###                     `PROJECT-VERSION'.
  41 ###
  42 ###     The following `make' targets must be available in the top-level
  43 ###     Makefile.
  44 ###
  45 ###     dist            Write to $(distdir).tar.gz a source distribution of
  46 ###                     the package.
  47 ###
  48 ###     distcheck       As for `dist', but also build and test the project.
  49 ###
  50 ###  * The source distribution constructed by `make dist' must contain a file
  51 ###     $(distdir)/RELEASE containing the release name.  This isn't currently
  52 ###     tested, but it might be later.
